y invention relates to o volvo which may be used to control and direct the flow of a fluid through any one or through several of a number of filters in various directions.

Heretoiore in the' use of imrtaixi waterilters there has been disturbance of the li Itern i -ing material whenever the dimetion of the flow of vvater through' the filter has been e in passing from single to double ltermg, olviee versa, and this disturbance is not only-injurious to the filter itself, but it le dial for Figs. 8, 9 10, and' 11 are hoxie'ontelY the vnlve on the lines VIIIY the. der

. tablets also renders the filtering operation more or less imperfect The objeet'of my invention is to provide a valve for making such changes in such a man4 11er that the filtering materiel shell not be disturbed.

In Fig. 1 of the drawillngs I have shown my Vvolvo applied to a lilter'having two filteringfnde-rs A und B, the filter of that use in which the water passing to the filter through' the luw-water-supply pipe :s may be siughiltow'd*that is, caused to pass in two streams through the two pi es o and b, t0 and throowh the two filtering-cylinders A and B, unil thence to the servies-pi d-or the water muy ho doublo-iiltered-t lat is, it

rma be caused to pass from the suppl pipe 32 irst through the cylinder A an Ythrough the cylinder B before then 'it asses to the service-pipe, .4, or vico versa. Ilie filteringeylinders A end B "my bo washed, either one,

iiitliiltered water from the other of the two 'oyinernos by water passing from the sup'- ipy-.pipe' to the cylinder Vand Y thence by ipes a and b to the bottom of thecylin- YYand through this oyloder to the wastepipef. The means vby which these changes m the direction of the ilow of the water is sooomplished is the plug i, which may be turned to the desired position by n. suitable Wrench fitting on'the squared end h thereof` I will new describe my invention, so titel:

others skilled in the srt may menofeotnre and use the some. Y i

In the drawings, Figs. dial nso seenreclto'tho Y as the stein Yond plug of the valve rotate the dial rotates therewith. Fastoned to the ces- El and Vl', I show n ging of the valve is a pointer or index-inger s.

stem h of the plug that Thsfdisl is preferably marked at its middle tablet with nthe win'd Single-filterin f, whielris the'trst or ordinary position of t e valve. S 0n one side of this middle tablet is a tsblet marked Double-filtering left to night, auf! on the other side of the sil 'l0- ii tering tablet is o tablet marked Don loiiltering rightto'lef which indicate the socond ositions of the valve. At the two ends of t ie dial and beyond the doubleiltering Ynro tnblets.Y marked Washing right l1snfl1ssd"wss left hand, which indiente thethrd positions of thevalve. Those Ytablets when brought opposite the pointer s show the position of the plug of the valve in the casing, such position being the proper one for the operation indicated on the tablet.

In Figs. 2 and 3, which are vertical sectional views of the valve, and in Figs. 4, 5, and 6, which are horizontal sectional views, I have shown the lu 'i of the valve in its first position to sing eter the water-that is, the plug is in such position as to divide the water entering the valve-casing C from the supply-pipe a: into two streams, one stream passing to the cylinder A and the other stream gassing to the cylinder B. The valvecasing is provided With a supply inlet-port 2, which connects with the supply-pipe a supply outlet-port 3, which connects with the pipe a., leading to the cylinder A; a supply outlet-port 4, which is similar to the port 3 and connects with the pipe b, leading to the cylinder B; a discharge inlet-port 5, which connects with the pi e a', leadin to the valve from the bottom o? the cylin er A; a discharge inletport 6, which is similar to the port 5 and connects'with the pipe b', leading to the valve from the bottom of the cylinder B; an outlet-port 7, that connects with the service-pipe d, and a Washing or waste port 8, that connects with the waste-pipef.

The plug i of 2: valve is provided with certain channels 'ch may be brought into communication with the several ports in the casing by turning the plug on its axis. In the position of Figs. 2, 3, 4, 5, 6, and 7, which is the first position for single-filtering, the supply inlet-port 2 is in communication with the supply-plpe and the supply outlet-ports 3 and 4 are in communication with the pipes a and b and an open channel 1c, formed in the plu 1'. between t e port 2 and the ports 3 and 4, t us permitting the Water to pass from the ialixufpply-pipe :c to both cylinders A and B.

ter passin through the filtering material in the cylin rs A and B the water passes from the cylinders through the pipes a and b to the dischar e inlet-ports 5 and 6 in the valve-casing ang thence through the open channel o to the discharge outletport 7,

` which is in communication with the servicepi ed.

he lug i is provided with three separate channe s-c, the upper channel, which directs the flow of water from the supply-pipe a: in filtering; o the lower channel, which directs the iiow o water. to the servicepipe d, and m, the middle channel, which directs the low of dirty water in Washing out the cylinders and also the single-filtered water in doublefiltering.

In Figs. 8, 9, 10, 11, 15, and 16 the valve is shown in one of its ositions for the purpose of double-filtering, tllle port 2 being in communication with the supply-pipe and by means of the channel k 1t is 1n communication with the port 4 and pipe b, leading to the cylinder B; but it is cut oil from the pipe a mis cut off from the ports 5 and 7 by the vertical wall m; but it is in communication with the port 3, and the filtered Water from the cylinder B is thereby caused to pass through the port 3 and pipe a,to the filtering-cylinder A. The port 5 is in communication with the channel 0, and the double-filtered Water from the c linder A passes through the pipe a into the cliannel o and from this channel through the port 7 to the service-pipe d.

In Figs. 12, 13, 14, 17, and 18 I show the valve in one of its third ositions for the purose of washing one ci) the cylinders with Eltered water from the other cylinder, the port 2 being in communication with the suply-pipe :I: and the channel 7c, the channel k eing in communication with the port 4 and shut off from the ort 3 b the vertical wall 1c. The water from t e supp y-pipe passes into the cylinder B and through the same into the ipe b in the manner already described. he port 6 is in communication with the pipe b and also with the channel o,which channel is in communication with the port 5 and also with the port 7. Part of the filtered water from the cylinder B passes through the channel o to the port 7 and service-pipe d and part passes from the channel o to the port 5 and ipe a and thence through the cylinder A om bottom to to washi the filtering material with iltere Water. he port 3 is also in communication with the channel m, and as the waste Water passes from .the cylinder A through the pipe a to the valve-casing C it enters the port 3, passes throu h the channel m to the port 8, and through t is port to the waste-pipe f. This operation washes either of the cylinders with Water from the other without interfering with the sKpp-ly of filtered Water to the service-pipe d. t ough Ihave mentioned the plug t, this plu is in realit a shell having Walls to form c annels. `s construction enables the partition to be of such form and thickness as to prevent liability of leakage. At the lower portion of the valve-casing C is a ort 9 and ipe e, the port opening into the c annel o. pipe e 1s provided with a faucet e. By means of these parts the valve C may be drained.

The operation of double-filtering and of washing may of course be reversed-that is, the water ma be caused to pass first throu 'h the cylinder and then through the cylindger B in double-filtering; and in washing, the filtered water from the cylinder A ma be used to wash' the c linder B lby movi t e valveplug to the le t of the single-filtering position instead of to the right.

I have given the several ports names in accordance with their functions in single-filter- IOO TIO

ing', and these names have been retained throu hout the specication and claim, althoug the function may be different in the several positions of the valve.

The advantages of my invention result from the construction that enables the valve to be moved from single-filtering position to double-lteri in either direction Without assin throng the washing position, alec om t e construction of the plug that ailows the' water to pass through the various channels Without liability of leakage, and also from the location and connections of the channels and ports that result in a decrease of friction.

I claim- The combination of two filtering-chambers a valve-chamber having a suppl inlet-port connected to the raw-Water-supp y pi e, two supply outlet-ports connected to sei Eltering-chambers, two discharge inlet-ports also connected to the filtering-chambers, a discharge outlet-port leading to the servicepipe, and a washing or waste crt; and a plug adapted to said valve-cham er and provided with channels and ports adapted in the rst or single position of the plug to connect said supply inlet-port with said two supfily outletports and said two discharge in ports with seid discharge outlet-port; in the second or double-filtering ostions of the plug to connect the supply in et-port with the sugpl outletort leading to one filteringcham er Yand t e discharge inlet-port of said filtering-chamber to the su ply outlet-port of the other ltering-cham er,v and the discharge inletort of said last-named lterinchamber Wit the discharge outlet-port lea ing to the service-pipe; and in the third or Washing positions of the plu to connect the discharge inlet-port of one tering-chamber `with the discharge inlet-port of the other Eilteringchernber, and the su ply outlet-port of said last-named filtering-c amber with the Waste-channel and waste-port; substantially as described.

In testimonyr whereof I have hereunto set my hand.
